Just as the group velocity is similar to spectral dispersion, in that both correspond to the first derivative of refractive index with wavelength or frequency, the GVD is used similarly to the partial dispersion as they are both second derivatives with respect to wavelength or frequency. In addition to pulse broadening, chromatic dispersion may also make refraction angles at optical surfaces frequency-dependent, causing angular dispersion and frequency-dependent path lengths.

Ultrafast lasers are affected by dispersion significantly more than other laser types due to their broad bandwidth. As the group velocity is given as the first derivative of phase velocity with respect to frequency, the group velocity dispersion (GVD) is the derivative of the inverse group velocity with respect to frequency: (2)$$\text{GVD} = \frac{\partial}{\partial \omega} \left( \frac{1}{v_g} \right) = \frac{\partial}{\partial \omega} \left( \frac{\partial k}{ \partial \omega} \right) = \frac{\partial ^2 k}{\partial \omega ^2}$$.
